Expedition 12K Trail Race

Embark on an unforgettable journey at the Expedition 12K Trail Race, set for Sunday, April 26, 2026, in the breathtaking landscape of Whitehall, Montana. This challenging 12K event unfolds within Lewis & Clark Caverns State Park, offering runners an exhilarating experience across primarily single-track trails. Prepare for a course that boasts over 2,200 feet of vertical gain and loss, featuring sharp turns and winding paths that deliver sweeping, picturesque views of the Jefferson Valley.

Runners should anticipate diverse terrain, as typical race day conditions in late April often bring highs around 54°F and lows near 28°F, with a slight 5% chance of precipitation. While trails are generally dry and clear, be ready for the possibility of snow or icy patches. To fuel your expedition, two cupless aid stations will be strategically placed along the course, offering water, electrolyte drinks, and gels; remember to bring your own hydration vessel.

Beyond the physical challenge, the Expedition 12K promises a rewarding atmosphere. Registration includes chip timing, park entry, a custom race shirt, an additional custom item, and eligibility for top awards. Celebrate your accomplishment with a well-deserved post-race hot brunch and drinks at the finish line, embracing the spirit of camaraderie and the stunning natural beauty of Montana.
